ROTARY MOTOR.

Specification of Letters Patent.

Patented July 2, 191..

Application led March 20, 1917. Serial No. 156,162.

To all whom t may concern:

Be it known that I, JOHN O. WINES, a citzen of the United States, and a resident of the city and county of San Francisco, State of California, have made a new and useful inventionto-wit, Improvement in Rotary Motors; and I do hereby declare the following to be a full, clear, concise, and exact description of the same.

The invention relates particularly to rotary motors of the internal combustion type, having reciprocating pistons therein. One object of the invention is to provide a motor of this type, simple in construction, direct in action and capable of using efciently expansive force asa power.

Another object is to so assemble the working parts that leakage and friction are reduced to the minimum. f

In the specification and the annexed drawings, I illustrate the invention in the form Vconsidered by me to be the bestbut it is to be understood that the invention is not limu ited to such form because it may be embodied in other forms, and it is also to be understood that in and by the claims following the description, it is desired to cover the invention in whatever form it may be embodied. 1

In the accompanyingV one sheet of drawins.

l `Figure 1 isa side elevation of a motor the insulated commutator sector adapted to convey electrical ignition to the spark plug. In detail the construction illustrated 1n the drawings includes the stator 1 having a y suitable base 2 cast thereon. rllhe stator has an interior elliptical periphery, and for convenience in manufacture and accessibility is preferably divided horizontally and bolted together as indicated in Fig. 1. 'Ihe sides of the stator are suitably countersunk to receive the covers 3 and t bolted to the opposite faces thereof.

rIhe rotor 5 is concentric with and fixed to the hollow shafts 6 and 7 projecting from the opposite sides on the axis of the rotor and suitably journaled in the bearings 8 and 9, provided therefor in the covers 3 and 4. rIlle exterior of the rotor is parallel with the surface of the interior periphery of the stator, with which it approximates contact at the narrowest point of the stator, in the present instance on the horizontal diameter thereof, see Fig l. Y The shafts 6 and 7 form an integral part of or are fixed in the side walls l0 and 11 respectively of the rotor. The rotor is bored transversely on its diameter to receive the sleeve 12, slidable therein and operated and controlled by a stud 16 provided with an antifriction roller 111 engaging a cam slot 15 milled in the'side of the plate 4. The curve of the cam slot being plotted to time the reciprocations of the cylinder sleeve 12 to control the inlet and outlet ports for the various cycles synchronously with the operation of the pistons as hereinafter more fully described.v rIhe pistons 161 and 17 reciprocate in the rotor in opposed relation within the cylinder sleeve l2, the pistons being provided with the overhanging annular heads 18 and 19, respectively engaging annular recesses in the opposite ends of the cylinder sleeve, to limit the inward thrust of the pistons to maintain the fixed displacement of the combustion chamber 20, between the opposed inner ends of the pistons. Combustible fuel is admitted into the combustion chamber through the bore 21 in the hollow shaft 7 communicating with the carbureter 22, suitably connected to the fuel supply, not shown. The bore 21 through the shaft 7 terminates in a port 23 registering with the port 24 controlled by the stud 16 andthe cam slot 15, see Fig. 5, during the suction cycle of the piston which operates on the four cycle principle.

When the motor is turned by the self starter or by hand in initiating its operation, the centrifugal force throws the pistons outward from the center, increasing the volume of the combustion chamber limited and controlled by the ellipse of the periphery of the stator, the separation of the pistons creating a suction therebetween in the combustion chamber 20, the cylinder sleeve l2 being synchronously operated bringing the ports 23 and 24 into register. The suction between the pistons operates upon the carbureter to suck in the `carbureted mixture of air and fuel. The suction cycle reaching its maximum when the pistons are in the vertical position 90 from the position illustrated in Fig. 1, which is the maximum of the suction cycle. Continued rotation of the rotor causes the contour of the stator to force the pistons again together, compress 'ing the fuel mixture contained Within the combustion chamber between the inner ends of the pistons, until the pistons `again'reach the horizontalposition as illustrated in Fig. 1, which is the maximum of the compression stroke. The ports 23 and 24 are forced out of registry by the cam 15 just as the maximum of the suction stroke is passed. At or nea-r the maximum of the compression cycle, electrical ignition energy lis conducted through the cable 25 from a suitable source of supply, not shown, being grounded upon the stator as kat 26, the opposite Vend leading to the commutator 27, the leads 28 4conducting the current through the insulated terminal of the spark plug 29, causing a hot, igniting spark to jump across the terminals ofthe spark plug, exposed within the combustion chamber 20 through the port 30 "formed n the sleeve 12. The spark ignites `the compressed fuel within the combustion chamben'the lcombustion of the fuel expanding to force the pistons apart, this being the kpower stroke of the motor called the combustion cycle.

The outer end of the pistons bearing against the periphery of the stator cause a wedging or prying action, the leverage of which operates to rotate the rotor 5 until the pistons have reached the limit of their outward throw which would be the vertical position :(-see Fig. 1), which is the maximum of the combustion cycle, during which the expanding gases have exerted their power. At this `point the port 31 in the sleeve 12 is brought Vinto registry with the port 32 in the :rotor by the 4operation of the cam 15, the -port 31 zopening into the central bore 33 in the :shaft 6 permits the products of combustion y:to exhaust thereinto during the next cycle which is called the exhaust cycle, represented by the traveluof the pistons from the :maximum combustion cycle to the minimum of the exhaust cycle, represented by the pistons in Fig. 1, which :are thereby restored to theposition for initiating the suction cycle and the various cycles enumerated; 'consistingvin drawing in a charge of fuel compressing 1t, firing it, exhausting or. lscavenging out the the products of combustion. During'the combustion cycle or power stroke sufficient energy is stored in the fly wheel v34C fixed on the shaft '6, to carry the rotor through the succeeding cycles of suction, compression and exhaust.

Vthe centrifugal force exerted by the rotor.

rllhe interior mechanism may be lubricated by introducing a suitable lubricant with the fuel through the shaft 7, the oil being drawn outward and distributed by It is manifest that by a suitable arrangement of valves an expansive fluid, such as steam, compressed air, or the like, may be substituted for the combustible fuel, and introduced into the combustion chamber 20, with obvious results, in which case the -clectrical ignition would be dispensed with.

rlhe covers 3 and 4 are provided with lateral openings 34 through which air will be caused to circulate by the rotation of the rotor, lsuch circulation tending to vkeep the rotor at normal temperature.

It is obvious that the motor is reversible, in that it will operate in either direction, according to which direction it is started in.
